Benefits of Heavy-Duty Cast-Iron Wheels From RWM Casters

These high-quality wheels have no shortage of benefits. Here’s what our heavy-duty cast-iron wheels can offer:

  • Extreme weight-bearing capacities: Cast iron is an exceptionally strong material capable of supporting loads much larger than your average wheel. These wheels are one of our highest rated for capacity, capable of bearing up to 6,000 pounds.
  • Easy rolling capabilities: Even on the roughest of floors, heavy-duty cast-iron wheels will keep rolling. This helps to minimize the amount of effort it takes to transport heavy loads.
  • Appropriate for high-temperature applications: High temperatures demand a wheel that will hold up in these tough conditions. Our wheels are rated for use in temperatures up to 800 degrees Fahrenheit.
  • Resistant to water and the environment: These wheels can be used in outdoor settings and wet conditions (although they will rust over time).
  • Capable of withstanding exposure to chemicals, grease, and oil: Accidents happen, and caustic residue can get spilled on the floor. If this happens, our heavy-duty cast-iron wheels can withstand chemicals, grease, and oil, so you won’t have to put a halt to operations.

One of the greatest features of heavy-duty cast-iron wheels is their sustained durability, making them ideal for applications that require heavy loads and demanding conditions. Even if you have rough floors made of concrete or irregular surfaces, these wheels won’t be stopped.

While a great option for many applications, cast iron is not a suitable material for every situation. Don’t use these wheels on floors that need to be protected, as they can cause untreated concrete floors to deteriorate over time. If you need impact strength, as well, forged steel wheels are a better alternative.

Applications that heavy-duty cast-iron wheels are commonly used for include:

  • High-temperature settings, such as autoclaves, bakeries, smokehouses, curing ovens, and mobile powder coating racks
  • Manufacturing applications, such as aerospace, tire, automotive, construction, and heavy farm equipment
  • Warehousing applications, such as towlines and material handling
